Fantastic Elastic

Fantastic Elastic

Author: BBC Radio 4 December 11, 2024 Duration: 42:44

Brian Cox and Robin Ince expand their knowledge of elasticity with Olympian Bryony Page, comedian Jessica Fostekew & experts Dr Anna Ploszajski and Prof James Busfield from Queen Mary University of London.

What makes stretchy things stretch? Together our panel journey through different applications of elastic materials and examine, at the molecular level, what happens when we stretch a material and crucially what causes it to return to its original shape. This is especially pertinent to our guest Olympic and British champion trampolinist Bryony Page who has capitalised on elasticity in her 24 year long career. We discover that the bounce of a trampoline mainly comes from the elasticity of steel and how dependent this is on temperature. Cold temperatures are not only treacherous for trampolines; we explore how the cold proved fatal to the elastic components of both the Titanic and the Challenger space shuttle.

Plus we hear how scientists sometimes just can’t beat nature; natural rubber and spiders silk are two such cases. Anna Ploszajski takes us through some of the more inventive techniques scientists have engineered to produced more of these natural materials, including genetically engineering goats to be milked for silk.

Imagine a room where the biggest questions in the universe meet the sharpest, silliest wit. That’s the essence of The Infinite Monkey Cage, a BBC Radio 4 production hosted by physicist Brian Cox and comedian Robin Ince. Each episode gathers a panel of leading scientists, experts, and curious celebrities to tear apart a topic, from quantum quirks to cosmic mysteries. The conversation is a genuine collision of rigorous thought and irreverent humor, where a profound insight about black holes might be followed by a perfectly timed joke. You’ll hear complex ideas explored with clarity and a sense of shared wonder, never taking the science-or themselves-too seriously. This particular podcast thrives on that dynamic tension, making the frontiers of knowledge feel like a lively, accessible, and often hilarious dinner party debate. It’s a journey through the latest discoveries and enduring puzzles, all filtered through the unique perspectives of people who are genuinely thrilled to be asking "why?" Tune in for a consistently surprising and enlightening blend of intellect and laughter that proves exploring life, the universe, and everything doesn't require a solemn face.
